Why do some pumps need the full coating system?

Buried, submerged or aggressive-service pumps usually take the full blast, prime and top coat sequence, while indoor units may need less. Set the share from the coating spec.

What is budget variance telling me?

It is the coating budget minus the lot total. A positive number leaves room for extra prep; a negative number is the overrun to explain or re-quote.

How does lot size change the per-pump cost?

Booth and prep is charged once, so a larger lot spreads that fixed cost across more pumps. A small touch-up lot can carry a much higher cost per pump.

Can the full-coating share exceed 100 percent?

No. A share of one lot tops out at 100 percent. The page rejects a larger figure because it would claim more fully coated pumps than the lot holds.

Coating Cost per Pump Calculator

Price a coating lot from the pump count, the per-pump cost, the share receiving the full coating system and one fixed booth and prep charge. The budget check shows whether the lot fits before release.

What this calculator does

Coating cost for a pump lot with a full-system share, plus fixed booth and prep, against the budget.

Formula used

Variable coating cost = pumps to coat × coating cost per pump × share ÷ 100
Total coating cost = variable coating cost + fixed booth and prep cost
Coating cost per pump = total coating cost ÷ pumps to coat
Budget variance = coating budget − total coating cost

Inputs explained

Pumps to Coat: Pumps in this coating lot, from the work order.
Coating Cost per Pump: Blasted, primed and top-coated cost per pump.
Share Receiving Full Coating System: Share of pumps getting the full blast, prime and top coat.
Fixed Booth and Prep Cost: Booth time and surface prep charged once per lot.
Coating Budget: Budget this coating lot must stay within.

How to use the result

Best suited to quoting a municipal pump coating lot, checking a lot against a coating budget.
Surface prep needs can vary widely within one lot and move the real cost. Rework coats are outside the quote unless the quote includes them.

Current U.S. benchmarks

The U.S. has 21,668 machinery manufacturing establishments employing about 1,086,146 workers (Census County Business Patterns, 2023).
